After that I was turned - i. e., after I had turned away from Thee. In Jeremiah 31:18 it has the sense of turning to God.

Instructed - Brought to my senses by suffering. The smiting upon the thigh is a sign of sorrow. Compare Ezekiel 21:17.

The reproach of my youth - i. e., the shame brought upon me by sins of my youth.

After that I was turned - Converted from my sin, folly, and idolatry.

I repented - To conviction of sin, I now added contrition for sin. Conviction, in this sense of the word, must precede contrition or repentance. As soon as a man sees himself lost and undone, he is convicted of sin; when convicted, he begins to mourn. Thus contrition follows conviction.

I smote upon my thigh - My sorrow grew deeper and deeper; I smote upon my thigh through the extremity of my distress. This was a usual sign of deep affliction. See Ezekiel 21:12. It was the same among the ancient Greeks. So Homer: -

Ως εφατ' αυταρ Αρης θαλερω πεπληγετο μηρω

Χερσι καταπρηνεσσ,ολοφυρομενος δε προσηυδα.

IL. lib. 15:113.

"She spake: and with expanded arms, his thighs

Smiting, thus sorrowful, the god exclaimed."

Cowper.

- αυταρ Αχιλλευς

Μηρω πληξαμενος Πατροκληα προσεειπεν.

IL. lib. 16:124.

"Achilles saw it, smote his thigh, and said."

Cowper.

continued...

Surely after that I was turned I repented,.... Ephraim's prayer was answered; as he prayed he might be turned, he was; and when he was turned, then he repented, not only of sin in general, but of such sins as he had been particularly guilty of; not only of the grosser actions of life, but of inward sins, secret lusts and corruptions; even of sins of holy things, having now different sentiments, affections, and conduct: and this is what is called evangelical repentance, and is from the grace of God; springs from love; flows from a sight of God and a view of Christ; is increased by the discoveries of God's love, and is unto life and salvation; and this sort of repentance follows upon conversion; there must be first a true and real conversion before this evangelical repentance can take place:

and after that I was instructed I smote upon my thigh: as expressive of sorrow for sin after a godly sort; of indignation at it; and shame and confusion for it; and also of astonishment, at the mercy, forbearance, and long suffering of God, Ezekiel 21:12; and this humiliation follows upon spiritual instruction, which is previously necessary to it; "after it was made known to me" (u); as the words may be rendered; what a sinful, guilty, impure, and impotent, and unrighteous creature he was; after that he became acquainted with himself, and his wretched state and condition; when instructed either by the rod, or by the word, and by the Spirit of God, in the use of both, or either; when led into the knowledge of divine things; of the love and grace of God through Christ; of the person, offices, and glory of Christ; of the way of life and salvation by him; and of the doctrines of pardon, and righteousness, and acceptance through him:

I was ashamed, yea, even confounded, because I did bear the reproach of my youth; in his conscience; the sins and follies of his youth being presented and set before him, and he convinced of them, was filled with shame and confusion at the remembrance of them; which is a common thing when a man is thoroughly awakened and converted, and is brought to true repentance and humiliation. So the Targum,

"because we have received the reproach of our sins, which were of old?''

(u) "et postquam ostensum est mihi", Pagninus, Vatablus; "ostensum fuerit", Junius & Tremellius; "et post notum est mihi", Montanus.

Surely after I was turned, I repented; and after I was instructed, I smote upon my {z} thigh: I was ashamed, and even confounded, because I bore the reproach of my youth.

(z) In sign of repentance and detestation of my sin.

31:19 Surely - After God had changed our hearts, we repented. I smote - After God had instructed us, by his prophets, by our afflictions, and by his Holy Spirit, we smote upon our thighs in testimony of our sorrow. The reproach - The just punishment of the sins which I had long ago committed.

Margin repented

See Scofield Note: "Zech 8:14".

19. after that I was turned, I repented-Repentance in the full sense follows, not precedes, our being turned to God by God (Zec 12:10). The Jews' "looking to Him whom they pierced" shall result in their "mourning for Him." Repentance is the tear that flows from the eye of faith turned to Jesus. He Himself gives it: we give it not of ourselves, but must come to Him for it (Ac 5:31).

instructed-made to learn by chastisement. God's Spirit often works through the corrections of His providence.

smote upon . thigh-(Eze 21:12). A token of indignant remorse, shame, and grief, because of his past sin.

bear . reproach of . youth-"because the calamities which I bore were the just punishment of my scandalous wantonness against God in my youth"; alluding to the idols set up at Dan and Beth-el immediately after the ten tribes revolted from Judah. His sense of shame shows that he no longer delights in his sin.

31:18-20 Ephraim (the ten tribes) is weeping for sin. He is angry at himself for his sin, and folly, and frowardness. He finds he cannot, by his own power, keep himself close with God, much less bring himself back when he is revolted. Therefore he prays, Turn thou me, and I shall be turned. His will was bowed to the will of God. When the teaching of God's Spirit went with the corrections of his providence, then the work was done. This is our comfort in affliction, that the Lord thinks upon us. God has mercy in store, rich mercy, sure mercy, suitable mercy, for all who seek him in sincerity.
